  • Improper network stack configuration
  • Incorrect subnet or IP address settings
  • Exceedingly stringent security software and firewall settings blocking network access

Fortunately, the solutions to this issue are quite simple and actionable, as explained below.

How to Fix Cannot Connect to 5 GHz Wi-Fi in Windows Error?

One easy and potential way to fix the issue of your PC not connecting to the 5 GHz Wi-Fi is to update the driver from the official website of the manufacturer.

Alternatively, you can also do it from the Device Manager by right-clicking on the network adapter and selecting the update driver and following the on-screen instructions after that.

If that does not help, you may try rolling back the driver to an earlier version and try connecting to the 5 GHz network.

However, before you start with the solutions, it is important to check a couple of things to ensure that your PC supports 5 GHz frequency.

Check compatibility:

Open Run by pressing Windows Logo key and R key together > Type cmd > Hit Enter > Type netsh wlan show drivers > Press Enter > Look for Radio types supported section.

Here 802.11n, g, and b indicates 2.4 GHz network capability only and if it shows all these along with 802.11a and ac, it indicates 5 GHz network capability as well.

Check router settings:

Next, check the router settings to ensure it is broadcasting the 5 GHz network and is not set to limited compatibility mode or to a hidden SSID.

Check signal interference:

Then check for signal interference from other electronic devices around the router or from neighboring networks that may impact your 5 GHz Wi-Fi connections. Remove the devices that you suspect.

Now that you have checked the compatibility and support, try some other useful ways that might resolve the error in specific situations. These include:

  • Restart devices: Restart your PC or router by switching them off and turning on after some time to refresh network connections.
  • Perform a network reset: Go to Settings from the Start Menu > Network & Internet > Status > Network reset under Advanced network settings > Click on the Reset now button.
  • Update Windows: Go to Settings > Update & Security > Windows Update > Check for updates > Click Download if available > Click Install > Restart PC.
  • Remove 2.4 GHz network connectivity: Go to Settings > Network & Internet > Wi-Fi > Click on Manage known networks > Find the 2.4 GHz network in the list > Click Forget > Connect to the 5 GHz Wi-Fi band.

Now, if the above simple solutions fail, try fixing the issue by following a few relatively complex solutions as mentioned hereunder.

Note: For all fixes, it is necessary that the network card in your PC supports this particular frequency.

Also note that all these fixes may not be effective under all situations and settings. So, success is not guaranteed for each of these solutions. You will be better off if you try a couple of them if one does not resolve the issue.

If nothing helps, seek professional help or contact your network service provider.
